Frequently Asked Questions
How reliable is electrodermal screening?
There is a great deal of controversy in medicine today over the issue concerning techniques which are considered experimental, and which ones are to be adequately proven. There have been a variety of double blind studies using the electrodermal technology with very positive results in a number of countries including the U.S., Germany, Japan, China, France, Denmark, and Russia. There are many research papers and books written on this subject for example, 'Vibrational Medicine' by Dr. Gerber
What Do Bioenergetic Devices Do?
They measure a direct or indirect biological response to an evoked potential, which is the response of the body to energy or a change in energy. The response allows muscles, tendons, ligaments, cells, fluids, to move and the five senses to function and respond.
Is this Technology valid? Yes!
The technology is based on galvanic skin resistance, measuring skin resistance with an ohmeter. It has been shown that skin resistance is between 2,000,000 and 4,000,000 ohms, while at the acupuncture points, the resistance drops between 96,000 and 100,000 ohms in a balanced system. Research by Drs. Voll, Tiller, Tsuei, Pomeranz, Boucsein, Schaefer, Neijenhusen, Reichmanis, Marino & Becker and others all prove that the meridians and acupuncture points do exist and are valid points to use for evaluation.
What is ElectroDermal Screening (EDS)?
Originally this technology was called Electro-acupuncture According to Voll, (EAV), developed around 1950 by Dr. Reinhold Voll, engineer, medical doctor, dental surgeon, homeopath and acupuncturist.
Is the measurement of the energetic resistance of specific acupuncture points mainly on both hands and feet displaying numerically, energetic imbalances of a person and further determine specific products or techniqueswhich may help bring balance back into the body systems. Originally Voll's method consisted of measuring 180 points on the hands, feet and face. A pressure of 450 grams is applied and the reading is observed until a plateau is accessed. The energetic curve to reach this plateau determines the quality of the system being measured. Through Kindling, in Germany, other advances were made and the Bioelectric Function Diagnosis (BFD) approach was created. BFD dropped from 180 points to 56, and used other simplified methodologies.
- is a comprehensive term for all procedures based on measurements or therapy derived from Chinese acupuncture, using modern electronics.
What is electro-acupuncture according to Voll?
This is testing with a low voltage electrical charge which is introduced into the body, and the precise level of electric current conducted through the acupuncture points are measured. It includes information about various organ systems and musculoskeletal regions obtained by the numeric level of the readings. Various stimuli may be introduced, and any change in electrical conductance at various acupuncture points provides useful diagnostic information.
In reference to Ohm's Law, the models of the electrical equivalent circuits compare the electrical characteristics of components found in electronic devices. These electrical characteristics of components found in electronic devices also compare to the electrical characteristics of the body, which include resistance (conductance) and capacitance, which is caused when a barrier produces a buildup of a charge. The equivalent circuit shows that the body has electrical characteristics which change with dynamic ion concentrations, tissue permeability, cell-membrane binding and transport, and other functions. Engineers and scientists use these models to explain how the skin conductance measurement and EDS work.
The studies of Voll, Teichmanis, Tiller, Schimmel, and others have found than an inflammation of an organ causes increased ion concentrations. The increase of ions enhances the flow of electrons, so the resistance increases the conductance decreases. Tiller also found that after a current is applied for a few seconds, the resistance, may increase because the ion concentrations change. This causes the conductance to fall, which models the Indicator Drop (ID) of Voll.
What Energy is being screened in the body?
Processes in the body begin with energy and the structure and function of the body are sustained by energy. A biological process, including eating or illness, changes the structure or function of the body and causes the electrical resistance to change.
The change of the flow of electrons from one electrode to the other electrode provides a profile of the balance or imbalance of the meridians of the body. When flow of electrons is above or below the optimal value, there is an imbalance. By applying the stimulus of the probe the flow of electrons is registered by the ohmmeter, in a state of balance or imbalance. A different stimulus may be selected within the program to balance the flow of electrons, this may be done by determining a remedy, or cause of an imbalance or applying a treatment depending on which modules of equipment are used.
What is the Measuring scale?
Starts at 0 and goes up to 100. The value of 50 shows that the point measured is well balanced. Values over 60 up to 100 show inflammations of various stages. Values under 50 down to 10 show weaknesses and degeneration. Values under 10 are virtually never found. The indicator drop after arriving at the maximum plateau, may drop quickly, slowly or evenly. This gives specific information for the operator.
Who can use this technology?
A wide range of individuals may use this technology for information purposes in addition to other medical or non-medical applications for acquiring information. Countries, provinces and states may have specific regulations in terms as to whom may use these devices depending on government registration, or not. The professional doctor or practitioner may acquire information in addition to other sources.
Electrodermal testing systems utilize different energetic linkups with an energy reference bank containing substances being tested on acupuncture points for acupuncture point resonance effects. There are contained holding areas for testing remedies and multiple remedies recording meridian reasonance phenomena via a handheld acupoint probe. Frequencies of subtle energy directly enter into the body's meridians via special circuitry within the devices in order to find frequencies, which balance the unbalanced energetic system. (Gerber)
What are the Advantages and Disadvantages of eletro-dermal screening?
Certain pharmaceutical medications can effect the readings during a screening session. By observation, some medications may suppress a person's immune reactivity, resulting in false positive or other readings on the instrument. Skin testing may be suppressed in the same way, from hand lotions, which may have an insolating effect.
False readings may also occur in response to chemicals in the environment in which testing occurs such as reactions to perfumes, cleaners, etc.. Occasionally, for unknown reasons, the instrument fails to identify a food, chemical or inhalent to which a person by history repeatedly reacts.
The equipment is not clairvoyant, in determining all the possible reasons for ascertaining a particular reading. It assists by collecting energetic information to help determine pieces of a complex puzzle.
What is VEGA testing?
The vega-test methods were invented in 1978. The science of vega-test techniques is called bio-energetic regulatory techniques. The technique developed out of the principles of electro-acupuncture and medicament testing.
The practitioner no longer works on the many organ/gland measurement points but uses organ ampoules in a homeopathic D4 potency. The measurements are made on the measurement points, Allergy 1 or the Connective Tissue Degeneration 1, or Triple Warmer 1, right or left hand may be chosen for these points testing.
There are a variety of test kits available for testing on the mentioned test points for specific information.
The equipment consists of a voltmeter, testplate/honeycomb for product, an electrode and stylus.
How is an acupuncture point identified, through EDS?
Acupuncture points can be found by introducing a low voltage electrical charge into the body and then measuring the electrical resistance of the skin. The acupuncture points are more conductive or have less electrical resistance than the surrounding tissue.
Topographically, the measuring points are located with reference to certain fixed osseous points – usually the transition zone between the shaft and capitulum, or in the interstices of myofascial planes at the margins of muscles and tendons. The actual point is located on the skin 2-3 mm deep in the corium or subcutaneous tissue. Sufficient pressure is applied over the point to establish the degree of reproducibility of maximum artifact.
The instrument also has to yield a current polarized in the opposite electrical charge to that of the body. The current must be small or it will distort the measurement and change the physiology of the body. The positive pole is usually the stylus. EAV diagnosis is based on sending direct current obtained from a current source with a high internal resistance through the body using an exactly calibrated value derived from a phantom. Measurement carried out by this direct current as stimulus is a functional test just strong enough provoke a healthy body to bring about an equilibrium between the stimulus and its own reaction (stable value).
The hand electrode is placed in the patient's hand, while the stylus is stroked to the point of maximum deflection and then a measurement pressure is put on the acupoint. The indicator will drop back towards a lower value. This dropping back to a lower value is called an Indicator Drop (ID) and represents the most important reading in EAV. All IDs must be treated first.
Four consecutive points on each meridian must be measured in order not to miss an ID on a single point. Individual points may be used to diagnose problems with specific parts of specific organs. The hand electrode should be held on the same side that is being measured when meassuring the feet. A number of different results can be obtained from a reading of the acupoint.
- Balanced Reading
- Input voltage is matched by organ outpt voltage to give a reading of 50 (scale 0-100)
- An irritated or inflamed reading
- >60 due to excess discharge from the irritated organ, the intruding current exceeds the capacitance of the organ.
- A degenerative reading
- Initial normal or inflamed reading followed by an indicator drop (ID), that shows degeneration of the involved organ. An indicator drop below 30 is serious.
- A low reading or no reading
- due to organ inability to respond at all, a case of advanced degeneration.
The rate of rise of the indicator gives an indication of the state of energy within the organ. The slower the rate of the rise the less energy can be mobilized to balance the intruding current – the organ is fatigued.
